' 1'0 all w/wm it may concern:

Be itknown that I, MONROE 1). CoLBA'rir,

a citizen ofthe United States, residing at the city of Hanrpden,-county of Penobscot, State of Maine, have invented certain new and RS6.

furl Improvements in Carbureters, or which the following is a specification.

to improvements in carburete'rs- The objects of this invention are, first, to

. provide an improved carburete'r inwhich the ntroduct on of the air and the liquid hydrocarbon to the carbureter 1n 1proper proportions is automatically contro led; second, to provide an lmpi oved carburete'r which is 7 very simple and compact in structure and of large capacity and one which is not likely to get out of repair; third, to provide an im proved carburetor in which the necessity of placing the carburetor in the cellar or providing a special housing therefor is avoided Further objects and objects relating to 'structuraldetails will definitely appear from the detail 'description to follow.

i accomplish the objects of my invention by the devices and means described in the following specification.

The inventionfie clearly defined and pointed out in the claims; v I I .f

A structure embodying the features of my invention is clearly illustrated in the accorr.-

an in draw in s formin a art of this" b I e I specification, in which-' Figure 18 a central vertical sectional View through a stiucture embodying the features of. rnyinvention, the piping and regulatorsv being shown in full lines and the air-stoi age tank and the oilump being shown in conventional form.- ig. 2 is an enlarged longitudinal 'sectlonal view showing the structural details of the automatic oil-feed valve.

In the drawings similar letters of reference refer to similar parts in both views.

Referring to tiiejdrawings, I pi ovide a storage tank or reservoir A for the liquid hydr 0- carbon. This storage-tank is preferably buried in the ground or arranged in a suitable vaults The stolage-tank is provided with a suitable closureor cover a. The carbureter proper is arranged Within this storage-tank,

the cover a being of sufiicient size to perr'rritthe ready insertion-or removal of the sarne.

The caibureter consists of the main carbureting-chanrber B and an auxiliary carburet- The ,auxihai y carburetmglag-chamber B. chamber 3 1s cormected to the main carbu- .reting-chamber by a vertical tube Cl Both the main and the auxilizuy carbureting-- chambers are provided with horizontally-an.

ranged baffle-plates I), having perforations b" therein. The perforations or the adjacent baffle-plates aiearranged in a zigzag relation, so that the air andliquid hydrocarbon passing through-the chambers are forced to take a zigzag course. If desired, a suitablewicking or absorbant may be arranged between the baffle-plates." W ithin' the tube 0 are hollow screens c, forming par titions ac: oss'the same. Between these partitions is a suitable packing of abso bent material, as c.. l

. Theair is introduced into the upper or aux- Whiclroonnects the same with the air-stoi age tank-D. The air is supplied to this storagetank from a suitable pump or motor, not here illustrated. -'A suitable pressure-regulator D is provided for the airsupply pipe, so that the pressure of the air delivered is controlled. n

The air-delivery pipe D is arranged through the oil-supply tank E, which is arranged on the oil.+storage tank A above the .carbureter. Arranged Within the air-pipe D and connected to the oil-delivery tank E by a passage 0 is a. valve-casing E. This valvecasingispreferably centrally arranged in the air-pipe, so as to-be surrounded by the air iliary carbureting-charnber B by the pipe D,

passing through the air ip'e; The valve e is v varra n ed within the va veecasing E and is plovi ed, with a stem 6, which projects through the end of'the casing. On the end A service-pipe G is connected to the main carbureting chamber B near its bottom.

This service-pipe is provided with a pressureregulator G, so that the carbureted air or gas is delivered at a predetermined pressure. The oil is supplied to the oil-supply chamber by the pump P, which is connected to the storage-chamber at or near the bottom there of. A'pipe '1) connects the pump to the sup- Then the valve; e is in its roc,

IIO

ply-tank, the parts being here illustrated in conventional form. A check-valvev p is provided to prevent backfiow;

The pressure-regulators D and G are-set at about the same point, so that whenthe pressure in the carbureter is relieved by drawing the as or carbureted air from the service-pipe the air is admitted by the pressure-regulator D. of the supply-pipe. The

passage of air thro'figh the air-supply pipe forces the valve f from its seat, andthereby opens the oil-valve e, allowing the oil to flow past thesame into the air-supply pipe, from a which the air and oil pass together to the carbureter. As soon as the pressure in the carbureter again reaches a predetermined point the valves are returned to' their seats by the coiled s rin e thus cutting off the supply P g of both air and liquid hydrocarbon." The o1l-' valve 6 is so arranged that the amount of oil admitted therethrough is in pro er proportion to the amount of air admitte by the valve f. In the passage of the air and oil through the carbureter they are suitably mixed. The

packing of absorbent material 0 between the screensc absorbs the liquid hydrocarbon and holds the same in suspension, so that the air comes into thorough contact therewith.

If desired, a suitable packing of absorbent materialmay be arranged between the baffle plates b of the main and auxiliary carburetin -chambers.

w ith the parts thus arranged the amount of oil admitted to the carbureter is properly proportioned to the amount of air admitted thereto, and this is governed by the amount of carbureted'air or gas drawn from the service-pipe.

. By arranging the vcarbureter within the storage-tank the whole apparatus may be .buried in the ground a desired distance from the building, so that it is unnecessary to store any oil in the building to which gas is supplied. The structure is also verycompact and of large capacity in proportion to its size.

I have illustrated and described my improved carbureter in the form preferred by me on account of its structural simplicity arid compactness. I am aware, however, that it is capable of considerable structural variation without departing from my invention.

Having thus described my invention, what I I claim as new, and desire to secure by Letters Patent, is-
